Abstract

Abstract:

In order to determine the characteristics of electrical conductivity and thermo-electrical coupling effect on the tensile and fatigue strength of carbon fiber reinforced polymer (CFRP) composite laminates, the present paper focuses on two composite materials ([0]₈ UD and [45/90/-45/0]_s QI)which are prepared for the electrical and thermo-electrical fatigue experiments, direct current (DC) and alternating current (AC) from 1 A to 8 A are injected to the samples, and their temperature field and maximum temperature are monitored simultaneously in order to find itheir effect on the electrical resistance change. A simplified thermo-electrical analysis model is established based on the experimental phenomena and then the experimental results are compared with simulation results and a good agreement is found between them. The model is effective in describing the thermo-electrical phenomena at a steady state of temperature. In the condition of injecting of current, fatigue tests are prepared for different states of samples, the results show that the electrical current—no matter DC or AC or chang the value of current/frequency—has no obvious effect on the fatigue number of cycles, and has no obvious effect on the evolution of fatigue damage, but the temperature will raise while the current increases. Simutaneously, by monitoring the longitudinal resistance, it can be found that at certain loading level the resistance will augment while the number of cyclic increase. This phenomena shows inside of of sample may have some damage accumulating until the fracture of the specimen. Two models considering the relationship between electric resistance and strain based on the experiments are proposed to simulate the experiments, Model-1 is used to calculate the linear stage of strain (ε_xx≤0.4%) while Model-2 could be better used to simulate the nonlinear stage until the break of samples (ε_xx>0.4%).
